摘要
数学模型和甲型水驱特征曲线是油藏工程中两种重要的预测方法。为有效克服两种方法的局限性,近年来不少学者提出了数学模型与甲型水驱特征曲线联解模型。在前人研究的基础上,选取较具代表性的三种联解模型,从模型的特点及适用范围进行分析和对比,实例验证表明Hubbert模型与甲型水驱特征曲线联解法对油田整个生产阶段预测效果最理想,Rayleigh模型与甲型水驱特征曲线联解法适用于油田生产递减阶段,而广义翁氏模型与甲型水驱特征曲线联解法预测含水率偏低。
The mathematical model and waterflooding curve method are two important prediction methods in reservoir engineering.To overcome the limitation of each method effectively,in recent years,based on combined solution of the generalized mathematical model and waterflooding curves,new methods are provided.Three representative combined models and their characteristics are selected as well as applied ranges are analyzed,indicating that the combined method of Hubbert model and water drive curve of a type can be used to predict a whole life of oilfield best,the combined method of Rayleigh model and water drive curve of a type is adequate for the decline stage while the combined method of Weng model and water drive curve of a type predicts water cut lower.
